ORGAN STOP ACTION'.

Application filed February simplicity and economy in construction, its4 effectiveness in operation, and its compactness.

In the illustrative embodiment ot the in-V vention herein disclosed, they several stop actions ai'e provided with skeleton rollers which are operated or oscillated by means of traces in a manner generally similar to that disclosed in my latentsfNos, 1,131,8l4l and 1,145,867. In accordance 'with the present invention, more thancne, in the present instance two, trace is under the control oit a single manipulative device or piston, the specilic arrangement being such that when the. manipulative device is moved to `one position, one of the traces associated therewith is moved, and v-.fhen the device is moved to a second position, the othertrace is moved. i To eflect economy in space and cost of con-y stinction, thetraces under the control oi each manipulative device are mounted on one another.y p

Other objects will be in part obvious and in part pointed out more in detail hereinafter. 1 i

Theinvention accordingly consists in the features et construction, combinationo't elemen and arrangement of parts which will be Veirei'nplihed in the construction hereinalter set Jortl'i, and the scopey or the application oli which will be indicated in the appended claims. Y y f In the accompanying drawings, I 'have shoivn, more or less diagrammatically, one `en'ibodiment- Which the present invention may take, but it isfto be understood that this disclosure is by Way of exemplication only, as' my invention is susceptible'ofl various ymodifications and changes. For example', in the drawings, I have shown an electrical 3 1925. Serial No. 6,5l3.

le'lierringnv to the drawings in detail, IO

designates the skeleton rollers of one set of stop actions, and Il are the tablets `for individually oscillating;l these rollers. The numeral l2 designates the rollers' oit another set of stop actions adapted to be indivi dually manipulated in suitable manner, as by tab#`r lets The connections between the rollers andthe several registers ofy pipes is not illustrated, as these may be ot any suitable or Well-lmoivn type. yFor convenience in description, it may be assumed that the set or stop actionsv having the rollers l0 is associated With the pedal organ, and the ot` set or' stop actions having the rollers lL is associated with an organ played from a manual, for example the great organ. In actual practice, other sets of stops respectively associated With the choirr organ, the swell organ, or other section may vbe provided.

The stop action openatirne,` devices or rollers l2 are actuated in various selected combinations by traces l5 which, for concisenessv in terminology, are herein called the primary traces. rlhese traces have the usual cams or abutments 16 for selectively turningu the rollers in one direction or the other. The traces' are Yindividually operated or moved in one direction by respective magnets 18, and in the opposite direction by means of respective springs 17.

Mounted on the primary traces i5, and havingjmovement relativey thereto, are other traces 20 which, for convenience, are termed secondary or follower traces. These secondary traces have cams 2l adapted to actuate the' rollers l0. Preferably, but not necessarily, all of the traces are formed of `thin n it.

strips of metal, and' each secondary trace is positioned along one side ot its associated primary trace. rlhe seconcary traces are relatively shorter than the primary ones, as shown in the drawings. lila/ch secondary trace is so connected to its associa-ted primary one that, when .the latter has been movedL to operative position and the secondary trace is released, the secondary trace will move to operative position. To this purpose, the forward end of each secondary trace shown as having an ear entendH ing through a slot 23 inthe associated primary trace, and a spring 2l, connected at its respective ends to the primary trace and cui', is employed `for normally urging die second-v arv race lorwardly with respect to the primari" trace on which it is mounted. ll' wil be seen, by referring` to that, Awhen the secondary trace is in normal position, 'the ear 22 abn-ts against the forward Ytace of the opening As the primary trac is moved forwardly by a suitable manipulative device, the ,secondary trace -re tained in its normal position by a latchuig mechanism, hereinafter described* more in detail, thereby increasing the tension or the spring 253i. and bringing the rear :tace o' the slot 23 adjacent the ear 2Q olf the secondary trace 20. llllien the abore-mentioned latching device is released, the secondary trae'Y is moved forwardly by virtue of the te* siei of the spring 2l, the extent oit movement oi th secondary trace 2O being resn'icied by the slot il?" hen the manipulative device, which controlsl both traces, is released, the 't ces are returned to normal position in unison by the spring i7. The numeral 25 indicates a support on which the traces are mounted 'for sliding movement.

l cans common to all of the secom traces provided lier holding or latcliing these traces in inoperative or oil positions. ri`his means may taire any suitable forni, but here shown as including roller or cam 27 having a ledge 23 adapted to engage iunslanding projections 29 on the rear ends of the secondary traces. The roller 27 normally held in operative or holding position by a latch $30 cooperating with an arm 3l lixed to aniil extending from the rol 'The latch 8G may be controlled or opei by a magnet 32L to the operating magnets i8. Mounted hind the pistons for oscillating or swing A movement is a bar 35i having a contact arapted to engage, when the bar roche-il rearwardly, a contact 37, lthese contacts lieing in a circuit which includes the man 32. The bar is i'iermal,l y held in i position, as by means ol" spring 38, against an abutment 39. The pistons may be identilied as No. l, No. 2, etc. F r convenience, the respective associated magnets lo, primary traces l5, and secondary traces 2i) are similarly identified in the drawings.

The operation of the arrangement described is briefly as follows: Assuming that in setting up the traces, so that the various desired combinations of stops will be ready for use in the required sequence during the rendition of the programme or selection, it is desired to set the cams on the primary trace No. l, the piston No. 1 will be moved in until it engages the Contact 34 associated therewith, whereupon the operating magnet No. l is energized drawing the trace N o. l to the right` referringto F ig. l. The selected tablets 13 will then be manually rocked in a direction to oscillate the rollers 12, in the present instance ceunterelockwise, whereupon the associated cams 16 on. the trace No. l are thrown down. If it is desired to also set the cams on the secondary trace No, l, the piston No. l will be moved inwardly to its full extent, thereby rocking the bar with the result that Contact is closed between the terminals 36 and 37, causing energization oit' the magnet 32 and release of theroller 27. Then the roller is thus released, the secondary trace No. l will, under the influence oi its associated spring 24, move forwardly on the primary trace and then the tablets ll may be selectively rocked to selectively set the cams 2l on the ,econdary trace N o. l. After the cams have been thus selectively set, the piston No. l may be released or drawn out, thereby breaking the circuits through the associated magnets, with the result that the spring i7 associated with the primary trace No4. l will pull this trace and the associated secondary trace to their inoperative or left hand positions. The roller 27 will also be moved to the latching position shown in Fig. l by its own weight. The cams on the other traces may be set in a similar manner in accordance with the arrangement of a composition to be played. New', assuming that, during the rendition of the composition, it is desired to bring on a certain combination et steps by operating the primary trace No. i without operating the secondary trace associated therewith, the piston No. l will be moved to its first position where it closes Contact with the terminal S-l, causing energization or" the magnet No. l, whereupon the primary trace is drawn on and the set cams itil) lto tioncoul'd be made without departing from thereon will oscillate the respective selected rollers to move on or ofi' the desired register or registers. It itis desired to change the registers ot pipes `in the pedalorgan, the piston No. l may be moved to its full extent, resulting in the secondary trace No. l moving to the right and throwing the selected rollers l() in a direction'to move on or off the desired registers in the pedal organ. It it is desired to changethe registers in both the great organ and the pedal organ at the same time by means ot the primary trace No. l. and the secondary trace No. '1, the piston No. l maybe moved in to its 'full extent so that both the primary trace No. i and the secondary trace No. l are moved practically simultaneously. It is, of course, obvious that various combinations may be had and, if desired, the primary traces may be moved singly and the associated secondary traces subsequently, ora primary trace anda secondary trace may be moved at the same time. Theselected stop actions of the pedal organ may be thrown on by one of the secondary traces subsequently tothe operation oit its complementary primary trace and then, without disturbingthe setting oit rthose stop actions, the stop acti-ons ot the great organ, or other organs, may be changed by operating other primary traces singly.y

From 'the foregoing description, taken in connection with the accompanying drawings,

`it will be clear that each of the manipulative devices or pistons is differentially movable and, when moved into one position, a corresponding primary trace is operated, and when moved into a second position, the secondary trace associated with the operated primary one will move on its operative stroke, that is to the right. Prefer1- ably, when a piston has been moved to its first position, that is where it engages the associated contact 31h lthe organist will be apprised ot this tact by engagement ot the piston with the "bar 35, indicating that a` slightly greater pressure must be exerted on the ariston to rock the bar 35. It will further be seen that,`sinc`e the secondary traces are mounted upon the primary traces, the secondary traces require practically no addi'-k tional space, and the structure is very si1n ple and economical.L A greater number ot different combinations may be had than would be thecase it the cams for the pedal organ were carried on the same traces on which the cams for the other organs were mounted,` and this greater variety of combinations may be had without increasing the number of manipulative devices.

'las many changes could be made in the above construction and many apparently widely diiilerent embodiments of this inventhe scope thereof, it isintended that all matter contained in the above descriptitmv or shown in Athe accompanying drawings Shall be interpreted as illustrative and not in a limiting sense.
